I have the IRH ATH Switch helmet, i liked the look of the stripes but wanted to be able to have a brighter color for x-country. It still has yet to mold to my head(my head is more round in the front but squarish the back-i know really weird- and i do get a bit of mushroom head with it) but i it's starting to mold now that i'm wearing it more. It's only 2 years old(i've only worn it maybe 20 times) as my velvet helmet fits me like a glove but it's 10 years old so i've decided to hang it up for good and use my IRH.

With the blue to match my cross country vest

With the silver in(please ignore our matching goofy expressions) my face has gotten a bit rounder since then

If i was to buy a new helmet i would probably try a CO(GR8 as i'm at least a 7 1/4) as i've heard good things. The older tipperary helmets did not fit my head at all, i have yet to try the new ones(if they fit I might pick one up for trail riding as my helmets take a bit of a beating out on the trails-very overgrown -)
